You own a duplex, a triplex, or a quadruplex on the North Shore and are thinking of selling? ImmoMulti buys all three formats in this market directly — according to ImmoMulti estimates for 2026, the triplex sells a median 14% faster than the duplex on the North Shore, and its list-to-sale ratio exceeds 100% in some areas. But the answer to "which sells best" is not the same depending on whether you measure price per square foot (250–340 $/sq ft for the duplex), selling speed, frequency of multiple offers, or the available buyer pool. This guide compares the three formats with ImmoMulti's 2026 market estimates (indicative) to help you choose the right time and the right strategy for your multiplex on the North Shore of Quebec.
Who Buys a Duplex, Triplex, or Quadruplex on the North Shore?
Before comparing financial metrics, it's important to understand who buys what on the North Shore. The nature of the potential buyer pool is the most determining factor for a plex's liquidity.
The Duplex: Owner-Occupant as the Dominant Profile
A duplex — two units, often stacked or semi-detached — is primarily sought by buyers who want to occupy one unit and rent the other to offset their mortgage payments. This profile represents approximately 65 to 70% of duplex buyers on the North Shore, according to ImmoMulti's 2026 market observations (indicative estimate).
This buyer profile is subject to residential mortgage criteria (stress test, debt ratio) and is often limited by a budget below that of an institutional investor. Demand exists, but it is concentrated in a narrow price range and very sensitive to mortgage rate fluctuations.
The Triplex: The Balance Between Occupants and Investors
A three-unit triplex attracts both owner-occupants (who occupy one unit and rent the other two) and pure investors. This dual buyer pool creates stronger competitive pressure, resulting in shorter selling timelines and, often, multiple offers during periods of high demand on the North Shore.
Pure investors represent, according to ImmoMulti estimates, between 40 and 50% of triplex buyers on the North Shore (indicative proportion, not published by the APCIQ). This segment is less sensitive to residential rates as it often works with commercial financing.
The Quadruplex: Target of Professional Investors
From four units, the quadruplex is primarily sought by multiplex investors with an established portfolio. Financing a quadruplex can fall into the commercial category depending on the institution, which often requires a higher down payment (minimum 20%) and stricter eligibility criteria.
This narrowing of the buyer pool reduces the relative liquidity of the quadruplex — not because demand is low, but because qualified buyers are fewer. For the seller, this often implies a slightly longer timeline and sometimes the need to provide more complete financial documentation.
Which Format Offers the Best Price Per Square Foot: Duplex, Triplex, or Quadruplex?
Price per square foot is often the first metric cited in real estate discussions, but it can be misleading if not contextualized. For plexes, value comes primarily from the income generated — not from the square footage. Here are the estimated ranges from ImmoMulti for the North Shore in 2026, for indicative purposes.
| Type | Median Price (North Shore) | Typical Area (sq ft) | Estimated Price/sq ft | Premium or Discount |
|---|---|---|---|---|
| Duplex | $520,000 – $680,000 | 1,800 – 2,600 sq ft | 250–340 $/sq ft | Occupant premium +12% |
| Triplex | $680,000 – $920,000 | 2,600 – 3,600 sq ft | 220–300 $/sq ft | Market reference |
| Quadruplex | $820,000 – $1,150,000 | 3,400 – 5,000 sq ft | 195–275 $/sq ft | Liquidity discount −8% |
The duplex achieves the highest price per square foot, a mixed-use premium that owner-occupants willingly pay for the advantage of living in their own building. This premium can reach 10 to 15% compared to an equivalent triplex. However, this premium materializes mainly in established residential areas (Laval, Blainville, Rosemère) and less so in more industrial or transitional markets.
Important Nuance
Price per square foot is not the benchmark metric for professional investors. They use the GRM (gross revenue multiplier) and the cap rate (based on net income). A well-rented plex with a modest footprint can be worth more than a spacious plex with below-market rents.
What Are the Typical GRM and Cap Rates by Plex Type on the North Shore in 2026?
For sellers who understand how professional buyers evaluate their income property, the metrics that truly matter are the GRM and the cap rate. These two ratios determine the price a rational investor is willing to pay.
The GRM (Gross Revenue Multiplier)
The GRM divides the sale price by annual gross rental income. A GRM of 12 means the buyer pays 12 times annual gross income. On the North Shore in 2026, here are the observed ranges:
- Duplex: GRM of 13 to 16 (high occupant premium, rents often below market)
- Triplex: GRM of 11 to 14 depending on area and lease status
- Quadruplex: GRM of 10 to 13 (more units = income closer to market)
A high GRM is favorable for the seller as it means buyers pay more per dollar of gross income. The duplex benefits from a structurally higher GRM thanks to the occupant premium.
The Cap Rate
The cap rate is the preferred metric of multiplex investors on the North Shore. It corresponds to normalized net income (NOI) divided by the sale price, expressed as a percentage. The higher the cap rate, the stronger the current return — and the lower the price the buyer requires relative to net income.
| Plex Type | Average Cap Rate (North Shore 2026) | Seller Interpretation |
|---|---|---|
| Duplex | 4.8% – 5.5% | Low cap rate = high price relative to net income |
| Triplex | 5.2% – 5.8% | Balance point between premium and return |
| Quadruplex | 5.4% – 6.2% | Higher cap rate = liquidity discount partially offset by income |
"On the North Shore, a well-positioned triplex with up-to-date leases and little deferred work is the format that generates the most competition among buyers in 2026. It's the perfect balance between accessibility and return."

Which Sells Fastest — Duplex, Triplex, or Quadruplex on the North Shore?
A plex format's liquidity is measured by two indicators: the median selling timeline and the list-to-sale ratio (price achieved vs. asking price). These ranges are ImmoMulti estimates from its transaction observations on the North Shore in 2026 (indicative) and do not come from an APCIQ publication at this level of detail.
| Format | Median Timeline (days) | List-to-Sale Ratio | Multiple Offer Frequency |
|---|---|---|---|
| Duplex | 52–78 days | 97–101% | ~25% of transactions |
| Triplex | 45–65 days | 98–103% | ~38% of transactions |
| Quadruplex | 60–95 days | 95–99% | ~18% of transactions |
These figures confirm that the triplex is the most liquid format on the North Shore in 2026. Its median timeline is approximately 14% shorter than the duplex's and up to 35% shorter than the quadruplex's in the least active areas. A list-to-sale ratio exceeding 100% for some triplexes indicates overbidding situations.
Which Plex Format Sells Best by City on the North Shore?
Liquidity data also varies by city. On the North Shore, some markets are more active for triplexes, others for quadruplexes. Here is a summary by area to help you position your income property.
| City | Most In-Demand Format | 2026 Reference Cap Rate | Typical Timeline |
|---|---|---|---|
| Laval | Triplex | 4.9%–5.6% | 40–60 days |
| Terrebonne / Mascouche | Triplex / Quadruplex | 5.3%–6.0% | 50–75 days |
| Blainville / Boisbriand | Duplex / Triplex | 4.8%–5.4% | 45–65 days |
| Saint-Jérôme | Triplex / Quadruplex | 5.4%–6.0% | 55–80 days |
| Repentigny | Triplex | 5.1%–5.7% | 45–68 days |
| Mirabel / Saint-Eustache | Duplex / Triplex | 5.2%–5.8% | 50–75 days |
The city of Laval is the most liquid market for triplexes on the North Shore, with timelines often under 50 days for well-maintained buildings. Learn more about selling in Laval: see our complete guide to selling a plex in Laval.
What Selling Strategy to Adopt Based on Your Plex Format?
Here are concrete recommendations for each type of income property owner on the North Shore who is considering selling in 2026.
If You Own a Duplex
Your main asset is the occupant premium. To maximize this premium, make sure the owner-occupant unit is vacant or quickly vacatable — an owner-occupant buyer will pay more if they can move in without a legal delay. Also present rental income clearly: the buyer needs to easily visualize their cohabitation scenario with the income offsetting their mortgage.
If the duplex is fully rented with leases expiring far out, the occupant premium disappears and you compete directly with better-yielding triplexes. In this case, a direct sale to a professional buyer like ImmoMulti may be more advantageous than waiting for an owner-occupant who won't show up.
If You Own a Triplex
You have the best format for liquidity on the North Shore in 2026. To optimize your sale, prepare a complete financial summary: annual gross income, operating expenses, implied cap rate. Professional buyers will immediately compare your triplex to other properties on the market. See our article on mistakes to avoid when selling an income property to avoid leaving value on the table.
If You Own a Quadruplex or Larger
Financial documentation is your main negotiating tool. The more documented your quadruplex is (income and expense statements, renovation history, lease status, recent inspection report), the more you reduce the liquidity discount buyers will demand. A professional buyer needs no inspection and adds no financing conditions — that's the structural advantage of a direct sale for larger multiplexes.
Regardless of your format, the direct sale without a broker to ImmoMulti represents a serious alternative: a written purchase offer within 48 hours, $0 commission, as-is purchase, and notary within 30 days.
